摘要
介绍了一种用激光诱发红外光热辐射法对金属材料激光表面硬化层进行深度剖析的新技术。用这种技术，对经激光表面处理的锆合金（Ｚｒ－２．５Ｎｂ）表面硬化层的厚度进行无损检测，所得结果与常规的破坏性检验方法（剖面显微硬度测量）一致。
A non-destructive remote technique for obtaining depth profile of laser processed metals by laser- induced IR photothermal radiometry is reported. Applications to the inspection of laser processed Zr-2. 5Nb alloy samples are presented. Depth profiles obtained from this method are consistent with the profiles obtained from destructive methods such as microhardness testing.
